Do what everyone else does: get a job and build what you want in your spare time. There's also a few websites that list people trying to sell their small lifestyle projects. You might want to pick one up and see if it works for you. Even if you have no actual customers, you at least should have an idea of what problem you're trying to solve. Then search for that problem and see what's out there. If there are companies that are already doing it that's probably a good thing, because that means that someone has validated the market.
